Abstract

Objective: To examine executive functioning and cognitive inhibition as coexisting factors of behavioral inhibition among patients having Parkinson’s disease.
Methodology: Fifty individuals with a diagnosis of Parkinson’s disease at Recep Tayyip Erdogan Hospital, Bahawal Victoria Hospital and Nishter Hospital during April 2016 to March 2017 and fifty healthy individuals participated in the study. Participants completed Behavioral Inhibition and Activation Questionnaire, The Executive Interview 25, and Trail Making Test-part B.
Results: Patients with Parkinson’s disease showed impaired executive functioning, behavioral and cognitive inhibition in contrast with healthy individuals. Behavioral disinhibiting correlated with impaired cognitive inhibition and executive functioning in patients with Parkinson’s disease. Executive functioning was significant coexisting factor of behavioral inhibition.
Conclusion: Executive functioning is a significant coexisting factor of behavioral inhibition in Parkinson’s disease with cognitive inhibition.

Key words: Parkinson, executive functions, cognition.
